String Parsing Algorithm Pls

Below is the *s I have shown output from a router. I have this output stored ina string variable. I need to parse this string in a way that I can have only theusername as:dream407454dream402961stored in a list box one by one.

I have want to dicard any think like space " " or @.. just the username, I havea algorithm which is doing this but for long lists it tales at times upto 3 to 4minutes, can someone please develop some algorith I mean could code to help me

I, as u mentioned first tried to avoid the call to object properties and triedto minimize it as much as possible, this brought the processing time down from2.5 minutes to almost a minute, but still there was one text box having therouter output I was constantly reading until the textbox.length.Ok at this point I tried to findout about the string builders and downloaded asample about it, implemented that and u know what is the processing time now?guess!! 45 sec No, 30 No 10 No, it's less than or almost 1 Second, so what wasbeing done in 3 Minutes has now been achieved in 1 Sec, ALHAMDOLILAH that a helpfrom u came to me so useful that this application is again having interest forall, as earlier due to manipulation time people were a bit reluctant.
